Restart your Sharp Roku tv
When you experience any technical problem with your smart tv, then your first step must be restarting the tv.
Suppose you want to fix the black tv screen because it is not displaying pictures. First of all, power off and on your tv with the remote control device. Switch off your tv for 20-30 seconds.
If the tv screen does not give a picture, then remove the cable from the socket for 2 minutes and insert the cable in the socket after 2 minutes to power on the smart tv. Check if your tv is showing pictures or still it is dead.
In most cases, this step clears the minor glitches and bugs and fixes your issue, but sometimes power cycling the sharp roku tv does not troubleshoot the post so that you can carry on further tips.
Loose cable connections
If the tv screen goes black and does not display anything, one of the leading causes of this trouble is loose cable connections.
HDMI cables are used to connect different devices like DVD or roku cable boxes with your tv. So, make sure the HDMI cables are not broken and loose.
It is essential to fix these cables in a straight position because a slight twisting or tangling can lose or damage the cable, making picture issues to your tv.
Check all the HDMI cable ports and if you find any loose cables, then clean the port with a soft cloth and insert the cable tightly in the respective port.
If you locate a faulty HDMI cable, there is no other choice than to purchase the cable and then always buy a high-speed braided HDMI cable.
A braided HDMI cable is reliable and gives the best picture quality on your Sharp Roku tv screen. Dont forget to insert the cable in the right port because if your HDMI cable is in the wrong port, then the tv will not display any picture.
Check Your Remote
If there is no loose cable connection, then check your Sharp Roku tv remote control because it can also be responsible for Sharp TV’s black screen display.
Turn on other smart tvs with your remote control to check if it is working or not. If it does not turn on any device, then open the remote back chamber and remove the old batteries. Insert new quality batteries in the remote to check whether it works or not now.
Try to use the side panel buttons to operate the tv manually. If the tv shows pictures with manual control, then surely your remote control is faulty, and you need to replace it with new remote control.
See if the TV responds when you try the manual controls instead of the remote.
Update your TV software
Sharp Roku tvs come with software to provide you with different features, but it needs to be kept updated.
If your tv screen is black, but it has not affected the menu, then update your tv software. But if there is no menu display also, then you can skip this point.
Anyhow, if the menu is displaying, then open the settings menu on your TV. The next step is to go to system updates. Now, click the update option to download and install the latest software update on your tv.
Check the wall socket
A faulty wall socket is also responsible for the Sharp tv black screen. If there is no electric charge in your wall socket, then it will transfer current to your tv to switch on and show any picture.
It’s not challenging to check your socket because you can easily inspect it to see wheater it is faulty or working.
Removed the tv power cable from the socket and tried to put in another socket in the room.
If the tv immediately powers on, then obviously, there is no issue with the tv and cable, but actually, the main culprit is an outlet.
Plug in your smartphone charger in the previous socket to test whether it is charging or not.
If the smartphone is also not charging, then surely your socket is faulty, and there is something wrong inside the socket. You can hire an electrician to fix the faulty outlet.
Factory rest is always the last option whenever you troubleshoot any smart device. It is the last step because it not one clears all the minor glitches and bugs but also clears the device settings, accounts, and memory.
Every device has its own way of factory resetting, so you can get help from the Sharp Roku tv manufacturer’s manual to learn the steps to factory reset the tv.
